The Ubiquiti airFiber 5G34-S45 is a carrier-class 5 GHz dish antenna designed for long-distance Point-to-Point (PtP) wireless backhauls and high-capacity bridging. Operating within the 5.1 to 5.8 GHz frequency band and offering a massive 34 dBi directional gain, the AF 5G34-S45 provides the high RF isolation and gain required to establish ultra-stable, multi-gigabit wireless links over vast geographic distances.
Engineered with Slant 45° dual-polarization technology, the AF 5G34-S45 rotates the signal polarization by 45 degrees relative to standard vertical/horizontal antennas. This advanced design dramatically reduces co-location interference and cross-talk in dense RF environments, leading to superior Signal-to-Noise Ratio (SNR) and higher Modulation and Coding Scheme (MCS) rates. Designed to integrate directly with airFiber AF-5X and AF-5XHD radios, the antenna features a built-in radio mount and protective weather-proof radome cover. Its heavy-duty mounting hardware includes dual pole brackets and precise elevation/azimuth alignment adjustments for rapid, secure installation.
